T0 025 20 7mm it may concern Be it known that I, JAMEs Been, a citizenof the Dominion of Canada, of the city of Peterborough, in the county ofPeterborough, in the Province of Ontario, Canada, have invented certainnew and useful Improvements in Railway-Chairs, of which the following isthe specification.

My invention relates to improvements in railway chairs and the object ofthe inven-- tion is to provide means for holding the rail ends togetherso as to retain them in absolute alinement one with the other allow of afree limited longitudinal movement and in which there will be no dangerof the rail becoming loose by vibration due to passing trains and itconsists essentially of a chair body provided with a centrallongitudinal groove into which the base flanges of the rail ends fit andinwardly presented side grooves located at each side of the centralgroove of the chair body, the base of such grooves being parallel withthe rail ends and the side wall edge of such grooves converging inwardlyfrom each end of the chair body toward the center of the body oppositethe rail joint and wedge pieces fitting between the web of the railandthe inwardly converging edge portion of the side groove wall of thechair body, and a flange like extension extending laterally outwardlyfrom each wedge piece into the inwardly presented side grooves of thechair body, notches formed in the outer edge of each flange likeextension, orifices formed in the chair body above and below suchnotches through which notches suitable spikes are designed to extend andprojections extending upwardly from the base of the central groove ofthe chair body into slotted recesses formed in the bottom face of thebase flange of the rail as hereinafter more particularly explained bythe following specification.

Figure 1, represents a perspective view of my rail chair supported upona suitable sleeper and in which the rail ends are shown secured inposition. Fig. 2, is a sectional plan taken through the rail immediatelyabove the chair. Fig. 3, is a similar view to Fig. 2 showing the upperwall of the inwardly presented side grooves of the chair body removed,the portion forming the base of the groove being in section. Fig. 41, isa longitudinal sectional view. taken through the center of the railends. Fig. 5, is a cross and yet section on line 00-y Fig. 4:- Fig. 6,is a cross section online w Fig. 2.

. In the drawings like letters of reference indicate corresponding partsin each figure.

1 and 2 indicate the rail ends.

3 indicates in Fig. 1 a portion of a sleeper.

4- indicates the chair body resting upon the sleeper.

5 indicates a longitudinal groove formed in the upper face of the chairbody and into which the base flanges P of the rail fit.

6 and 7 indicate side ribs formed on each side of the upper face of thechair body. 6 and 7 indicate inwardly presented grooves formed in theside ribs 6 and 7 The bases of the grooves'6 and 7 extend parallel withthe side of the chair body and the side faces of the rail ends 1 and 2.The inwardly presented edges formed by the portion 8 forming the upperside walls of the grooves 6* and 7 incline inward toward the rail fromboth ends of the chair body to the center of the chair body opposite thejoint between the rail ends 1 and 2.

9, 9 indicate wedge pieces having comparatively broad outer ends andnarrow inner ends. The wedge pieces are driven into place between thevertical web of the rail ends 1 and 2 and the inwardly converging edgesof the wall portion 8. Each of the wedge pieces 9 is provided with alateral outwardly extending flange portion 9 which fits into the grooves6 10, 10 indicate notches formed in the edges of the flange likeextensions 9*. The notche 10, when the wedge pieces are driven intoposition, are in vertical alinement with orifices 11 and 12 formed inthe upper and lower walls of the groove 6 (see Fig. 6).

13, 13 indicate projections extending upwardly from the chair body intorecesses 13 formed in the bottom face of each of the rail ends. Therecesses 155* permit of a limited longitudinal movement of the rail whenthe rail expands or contracts due to a climatic change.

From this description it will be seen that all that it is necessary todo when securing a rail is to place the chair upon the sleeper, placethe rail ends in the longitudinal groove 5 and then drive the wedgepieces 9 between the vertical webs of the rail and the inwardlyextending edges of the grooves 6*. When the wedge pieces 9 are drivenhome the chair may be spiked down by driving the spikes through theorifices 11 and 12 and longitudinal movement of the rail when sub-vnotches 10 into the sleeper. By such con struction the rail ends areabsolutely held in a rigid position and cannot work loose, as is oftenthe case when connected together by fish plates now commonly in use, andin which there is no danger ofi the rail ends becoming loose due to thegradual loosening of the spikes holding the rail by the continualvibration of passing trains and at the same timeI have provided such ameans, which although holding the rail securely in absolutealinement,will allow of the free ject to climatic changes.

What I claim as my invention is. V 1. A rail chair comprising a chairbody provided with a longitudinal groove into which the base, flanges ofthe rail ends are designed to fit, upward extensions extending alongeach edge of the chair body and provided with inwardly presentedgrooves, the upper Wall of which is inclined from I 7 each end ofthechair body toward the center'of the chair body, wedge pieces providedwith lateral flanges designed to fit into the aforesaid grooves andnotches through which designed to extend.

' 2. A rail chair comprising provided with a central longitudinal grooveinto which the base fianges'of the rail ends are designed to fit, upwardextensions eX- tending along each side of the chair body,

the upper portions of the inwardly present- 35 the chair to the centerand ed faces of which are inclined; inwardly from each end of the lowerportions of to the rail, and wedge chair body from each end and havingportions bearing'against the inwardly'inclined portions and portionsbearing against the parallel portions of the chair body.
